Resumo de Recurso

top-down processing
  1. use information acquired through experience to make sense of sensory information - contrasted with bottom-up processing which uses information present in the sensory stimulus
    1. Gregory's constructivist theory of perception emphasises importance of top-down processing - while sensory information is the basis for perception it is not in itself sufficient
      1. use existing knowledge to form perceptual hypotheses which are then checked against sensory data - supported with visual illusions e.g. Muller-Lyer - adjusted through size constancy
        1. support from tests with Bete people live in jungle with no corners show little susceptibity to illusion
          1. illusion explained in terms of what is in the stimulus - suggested perceptual compromise between actual line length and figure it is a part of
        2. importance is challenged by Gibson's theory of direct perception
          1. important because it integrates top-down and bottom-up processing in a theory of perception
            1. criticized for over-estimating role of top-down processing and underestimating richness of sensory data
